China Procurement Expert | Sourcing agent in China

I’m Mara, founder of Ulinko LLC and a China-based sourcing and procurement partner specializing in new-energy and infrastructure products. I help international importers, distributors, solar installers, EPC companies, developers, and brands identify reliable Chinese manufacturers and manage the complete procurement process. My main product categories include: • Solar and energy storage: solar panels, inverters, lithium batteries and battery systems• Electric mobility: e-bikes, electric motorcycles, electric vehicles, chargers, controllers and related components• Modular construction: container houses, offices, showrooms and prefabricated buildings My services include: • Manufacturer identification and supplier verification• Technical specification and quotation comparison• Factory communication and price negotiation• Sample and private-label coordination• Production monitoring and quality-control coordination• Packing, consolidation, export documentation and logistics support For technical products, I do more than provide supplier links. I compare specifications, identify whether a supplier is a manufacturer or trading company, review available certificates and warranty documents, and clearly report any missing information or commercial risks. Through Ulinko LLC, I help clients build, manage and optimize their supply chains in China from initial research through production and shipment. My fees are agreed directly with the buyer. Supplier quotations are documented, and I do not accept undisclosed commissions from factories. Send me your product requirements, destination country, estimated quantity and target delivery date. I’ll recommend a practical sourcing and procurement plan.
